now.md: bank fp16-fairness reversal + PR #1486 native fusions + #1474 verdict

[justinchuby]

Coordinator campaign-brain update (doc-only, .squad/identity/now.md).

• Bank the honest fp16 fair-test reversal: qwen3.5 fp32 'moats' were export artifacts; fp16io same-graph is ~2.1x ORT-ahead (magnitude flagged unverified pending a real ORT captured harness).
• Record PR Fuse SSM/linear-attention reduction: drop fp32 cuDNN ReduceSum round-trip on native decode #1486 native decode fusions (+8.9% qwen3.5-0.8b-hybrid, byte-identical, capture preserved).
• Record CUDA 机器验证计划:#1186 内存重构 Phase 1–7 全栈测试指引 #1474 memory-stack verification verdict (6 deterministic async-deferred-release GPU test failures; no decode regression).
